The Human-Computer Communications Laboratory (HCCL) was established in 1999. Our vision is to leverage the powerful confluence of massive of computing, communication and content to derive intelligence in a form that is amenable to effective access, visualization and utilization for humans. Our mission is to foster interdisciplinary research and education in human-centric information systems. The scope of our study includes how interactive and intelligent human-computer interfaces to information should be designed and realized, in order to enable users to accomplish their desired tasks in smart, effective and efficient ways.

Guided by our mission, HCCL supports research areas including but not limited to: speech recognition, spoken language understanding, speech generation and synthesis, conversational systems development, audio information processing, multimodal and multimedia interface development, multi-biometric authentication, intelligent agents, mobile computing and e-learning.

E-Commu-Book is developed by HCCL in collaboration with Hospital Authority. The objective of E-Commu-Book is to help people with severe speech and/or language impairments communicate.

E-Commu-Book’s features include:
- A collection of 218 images of daily vocabulary under 14 categories (actions, feelings, social life, food, fruits, vegetables, drinks, clinic visit, places, commodities, clothes, people, transportation, and the miscellaneous)
- Automatic Cantonese output when an image is clicked
